Pennsylvania's tougher teen driving law goes into effect Tuesday.  

Under Lacey's Law, teenagers need more practice behind the wheel and face more restrictions once they do get their junior license.

The law was named for Lacey Gallagher, a Philadelphia teenager who was killed in a crash on the Pennsylvania Turnpike in 2007 while riding with six other teenagers on prom night. 

One of the three main parts to the law is an increase in the number of hours a permitted driver must have in order to get his or her junior license. 

"Permit holders now have to complete 65 hours of training before they can go for a junior driver's license," said Ofc. Bryan Losagio, Salisbury Twp. Police Dept. in Lehigh Co.  "It used to be 50." 

That's 15 extra hours behind the wheel, and the additional hours must be done in certain circumstances. 

"Ten [hours] must be done at night and five [hours] must be done in inclement weather," said Andre Wilkerson, owner and instructor of Easy as ABC Driving School.

"Adding a few extra hours of training, it's just going to make things safer for them, and give them more experience," said Losagio.

The second main part of the new law restricts the number of passengers a junior driver may have.  For the first six months, a teenage driver cannot have more than one passenger under 18 who's not an immediate family member. 

"It can be more than one if it's immediate family, but if it's a friend, you're only allowed to have one friend in the car," said Losagio.

After the first six months, Losagio said a junior driver can have up to three passengers, who aren't family, only if the driver hasn't been convicted of a driving violation or been responsible for a reportable crash.

The third part of the law requires drivers and passengers who are under 18 to wear their seat belts.  If not, it's now a primary offense.

"Primary offense means if an officer sees you not wearing a seat belt, or your passenger is not wearing a seatbelt, he can pull you over and write you a citation," Wilkerson said.

Losagio said police departments across the state plan to take that seriously. 

"If you don’t have your seat belt on and you're under 18, expect to get a ticket," said Losagio.
